mysqli_fetch_array (PHP 5) mysqli_fetch_array (no version information, might be only in CVS) result->fetch_array -- Fetch a result row as an associative, a numeric array, or both DescriptionProcedural style: mixed mysqli_fetch_array ( mysqli_result result [, int resulttype] ) Object oriented style (method): class mysqli_result { mixed fetch_array ( [int resulttype] ) }
Returns an array that corresponds to the fetched row or NULL if there are no more rows for the
resultset represented by the result parameter.
mysqli_fetch_array() is an extended version of the
mysqli_fetch_row() function. In addition to storing the data in the
numeric indices of the result array, the mysqli_fetch_array() function can
also store the data in associative indices, using the field names of the result set as keys.
Note: Field names returned by this function
are case-sensitive.
Note: This function sets NULL fields to
PHP NULL value.
If two or more columns of the result have the same field names, the last column will take
precedence and overwrite the earlier data. In order to access multiple columns with the same
name, the numerically indexed version of the row must be used.
The optional second argument resulttype is a constant indicating what
type of array should be produced from the current row data. The possible values for this parameter
are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH. By default the
mysqli_fetch_array() function will assume MYSQLI_BOTH for this parameter.
By using the MYSQLI_ASSOC constant this function will behave identically to the
mysqli_fetch_assoc(), while MYSQLI_NUM will behave identically to the
mysqli_fetch_row() function. The final option MYSQLI_BOTH will create a single
array with the attributes of both.
Return Values
Returns an array that corresponds to the fetched row or NULL if there are no more rows in resultset.
ExamplesExample 1. Object oriented style <?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
$result = $mysqli->query($query);
/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
/* associative and numeric array */
$row = $result->fetch_array(MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);
/* free result set */
$result->close();
/* close connection */
$mysqli->close();

Example 2. Procedural style <?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
$result = mysqli_query($link, $query);
/* numeric array */
$row = mysqli_fetch_array($result, MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);
/* associative array */
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
/* associative and numeric array */
$row = mysqli_fetch_array($result, MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);
/* free result set */
mysqli_free_result($result);
/* close connection */
mysqli_close($link);
